Petit-Saut Dam, Hydroelectric power station in Sinnamary, French Guiana.
Petit-Saut is a hydroelectric power station built across the Sinnamary River to generate electricity using the water's natural flow. The facility relies on turbine technology to convert this flowing water into power for the surrounding regions.
The project took shape in the late 1980s when authorities decided to build a major power facility for the territory. Construction moved forward rapidly and operations began in the early 1990s.
The dam represents how people in the region came to rely on locally generated hydropower rather than imported energy sources. It stands as a visible symbol of the territory's effort to develop its own industrial capacity.
The location sits several kilometers south of the town center and is accessible by road. Visitors should be prepared for hot, humid tropical conditions and know that the area sits deep within rainforest.
The water reservoir behind the dam is far larger than most people expect and has transformed portions of the rainforest landscape. This created lake now functions as its own ecosystem within the wider region.
